Inventor: GYENES PETER IVAN
IPC: B60S3/04
Filed: 1962-07-04
Abstract: In a vehicle-washing device (see Div B7) a cylinder having a piston 40 contains detergent on one side 42 of the piston and is connected to the main flow on the other side 41 to provide a supply of pressure water.  Detergent is ejected through a detergent supply pipe into the main flow downstream of a restriction therein and of the pressure water supply pipe.  A regulating valve is incorporated in the detergent supply pipe. The piston rod tail 43 extends through the cylinder end-cover and actuates an indicator, and a spring 45 returns the piston when the water supply is interrupted to enable the cylinder to be recharged.

Abstract: 1,207,420. Pipe joints. SMITH & JOHNSON (SALES) Ltd. 3 June, 1969 [4 June, 1968], No. 26425/68. Heading F2G. A pipe joint comprises a pair of matching flanges 12 and 14 of pipes 10 which are provided with opposed annular frusto-conical surfaces 26, 32 and radially inner and outer annular axially-extending shoulders 48 and 50 defined by projections 28 and 34 on flanges 12 and 14 respectively, and an annular dished gasket 16 which is of initially rhomboidal radial crosssectional shape, Fig. 2 (not shown), between the frusto-conical surfaces and which is deformed to an 8-shaped configuration in radial crosssection when the flanges are drawn together, the crests of the S sealing against the frustoconical faces. The arrangement permits flexing of the joint under bending loads without the seal breaking down. The cross-section of the gasket is of rhomboidal shape with both pairs of opposite sides being inclined in the same direction relative to the gasket axis prior to deformation to provide sharp edges which engage in the roots of the corners between the frusto-conical faces and the shoulders.

Title: Improvements in refuse containers

Filed: 1938-03-30
Abstract: 514,423. Refuse containers. WALKER BROS. (WIGAN), Ltd., WALKER. D., and ELFORD, E. J. March 30, 1938, No. 26542/39. Divided out of 513,782, [Group XXXII]. [Class 26] A container for the collection and transport of refuse, is formed with a continuous or dnterrupted flanged band extending round it preferably above mid-height for engagement with a yoke, girdle or other suitable lifting-means. As illustrated for use with the refuse-collecting vehicle described in Specification 513,782 the container is provided with the flanged band 49a which is engaged by the two-part embracing and securing ring 49 mounted on trunnions and carrying rollers 56 engaging guide rails 47, also being fitted with eyes for the attachment of cables 61 running to a winch 66. As the container is hauled up the guides, the projecting arms 59 on the ring engage stops 78 and rotate it into the dotted-line position 44. Preferably the securing ring is fitted between upper and lower flanges on the container band with a certain amount of play between the ring and the bands, thus allowing the tipped container to move relatively to and bump against the ring to dislodge sticking contents. Also, during the inversion, projections 95 on the hinged lid of the container are arrested by ramps 96 so that the lid is retained and thus opened while the body of the container completes the tipping- movement. At the same time the continued forward movement of the container slides the opened lid into the position shown at. 97. In some cases the projections 95 are detachable and are fitted to the lids when the container is ready for hoisting. In some cases the lids themselves are detachable and are fitted to the containers during transport and emptying only. In such cases the hinge 100 ds fixed to the lid and is clamped adjustably to the container body by screw-mechanism which can be set so that the pointers 107, 108 are in line, thus positioning the members 95 correctly in relation to the ramps 96.

[A Specification was laid open to inspection under Sect. 91 of the Acts, March 28, 1934.] [Class 51 (i).] Grates ; ashpits.-A solidfuel furnace, adapted particularly for central-heating boilers, has a rotary grate 6 to which fuel is fed centrally in an upward direction by a worm 14 and which carries, on its periphery, scrapers 9 serving to convey ashes to an outlet in the base of an annular ashpan 8 concentric with the grate. The fuel is distributed by a fixed member 16, 17 which may be cooled by air passing therethrough to the fuel bed 22. The grate may be composed of ring-shaped bars 6, arranged to form either a flat or conical grate as shown in Figs. 2, 3 respectively, or radial bars 32, of the form shown in Fig. 6, may be employed. The grate is rotated intermittently from the worm shaft 14 through a mutilated pinion 12 which engages a toothed ring 11 secured to the members 7 supporting the grate bars. A fixed scraper may project through the wall of the furnace to remove ashes from the periphery of the grate to the ashpan 8, which latter may be fitted with an annular perforated plate 8<1>, Fig. 3, on which combustion of any unburnt particles is completed, the resulting ash being removed by upper extensions of the scrapers 9. Fig. 7 shows the grate structure disposed in a refractory-walled chamber 21 connected to the ordinary combustion chamber 30 of a boiler, the driving mechanism 28 for the grate and the air supply fan 29 being arranged in a gas-tight casing 25. To permit the speed of operation to be varied, the driving mechanism may comprise two electric motors designed to run at different speeds and switched in and out by a thermostat, or a variable-speed motor controlled by a thermostat may be employed.

Title: Improvements in or relating to circuit arrangements for producing a picture in response to a video signal

Abstract: 1,010,630. Television; cathode-ray tube circuits. TELEFUNKEN PATENTVERWALTUNGS GESELLSCHAFT. June 29, 1964 [June 29, 1963], No. 26763/64. Headings H4F and H4T. In a circuit arrangement which increases the slope of a cathode-ray tube by having a relatively low bias potential at the second control electrode and in which the video signal varies the potential of the cathode of the tube relative to the potential of the two control electrodes in the same sense, both electrodes causing picture modulation, the picture brightness control is arranged to adjust concomitantly the biases in the same sense applied to the control electrodes. As shown, Fig. 1, a cathode-ray tube 1 of a television receiver has its first control electrode G1 connected to the sliding contact 3 of a potential divider 4, 5. The video signal 18 is fed to the base of amplifying transistor 8 from the collector of which it is applied to the cathode 11 of the tube. Potential divider 13, 14 having a permanently set tapping point 15 derives the bias potential for the second control electrode G2, and the resistance between the tapping point 15 and the sliding contact 3 is low compared with the total resistance of the divider 13, 14 owing to the high operating voltage of 500 v. In operation the sliding contact 3 is moved to change the brightness of the tube and as the potential divider 4, 5 is of low resistance compared with divider 13, 14 the percentage of the current flowing through 4, 5 which flows through 13, 14 changes only slightly, so that the potential difference between the control electrodes G1 and G2 remains almost unaltered, Fig. 2, not shown. Potential divider 2, 12 which adjusts the base bias potential of transistor 8 may replace the divider 4, 5. In a further embodiment, Fig. 3, contrast regulation is achieved employing a sliding contact 16 of a potential divider 17 which is connected in parallel with the load resistor 9, and owing to the fact that the upper end of the divider 4, 5 is connected to the cathode 11 and follows the potential fluctuations of the cathode, and the electrodes G1, G2 are coupled together in accordance with Fig. 1, the potentials at the electrodes G1 and G2 vary at the same rate as the potential at the cathode 11. The sliding contact of resistance 19 is used for the setting of the focusing potential for the tube.
